Hello. My name is Ursula, I am an ornithological veterinarian and have been treating and keeping owls for over 20 years. Over the years I have had owls of 11 species, including owls, in my care at a shelter for disabled birds. Sorry for the not-so-positive comment, I just couldn't pass by in silence..... Watched two videos of your owl and they horrified me. The owl is constantly screaming - this is not normal behavior and as a specialist I can say with certainty that the bird is constantly starving. What you perceive as a game is actually an attempt of a starving owl to swallow at least some object, tear off a piece of cloth, etc. Its hoarse cry is a cry for help. In the second clip, taken a year ago, the owl looks healthier, has normal paws, no signs of general infection, but it screams the same and rushes to a piece of food as a clearly VERY hungry bird. In this clip I see a very disturbing picture, his condition is dire: his paws are very swollen, his feet are swollen to the point where his toes can no longer bend, and there are feathers sticking out from the right side of his beak that are stuck together from nasal discharge. These are signs of infection that developed on the background of exhaustion (I suspect that exhaustion has already reached the degree of cachexia and the swelling of the paws is a consequence of renal failure developed from constant malnutrition).There are also a number of other signs that your bird needs IMMEDIATE specialist help, and the best thing to do is to take your owl to a bird hospital for a comprehensive examination and treatment. This should be done as soon as possible because your owl is dying. But first of all, remove the ammunition from his paws, because with such swelling, the ammunition interferes with the normal circulation of blood and lymph. And immediately start feeding the owl plenty of food! Owls, unlike diurnal birds of prey, are rarely obese, so it is difficult to overfeed an owl, it simply will not eat enough. Underfeeding, on the other hand, is very easy. The majority of owls, with which their owners contacted me, died of exhaustion. I hope that you love your owl and will listen to my advice. I wrote from the bottom of my heart, with the best wishes.
